An innovative six point HyLink radio transmission level system, supplied by leading level measuring specialists Hycontrol, is providing crucial operational data on the contents of screen house bins at Lafarge’s Hafod quarry in south Wales, producing over 250,000 tons of grit stone per year. Level data from the screen house bins is transmitted simultaneously to the receiver in the crusher control room and to robust portable receiver units in the cabs of the two dumper trucks used to transport screened product around the site.
